1958 c. D. AUSTIN STEREOSCOPIC VIEWER AND cm HOLDER Filed Aug. '25, 1954 m MT m V D S E L R A H c A 7' TOPNEX United States Patent STEREOSCOPIC VIEWER AND CARD HOLDER Charles D. Austin, Cincinnati, Ohio Application August 25, 1954, Serial No. 452,007

1 Claim. (CI. 88-29) This invention relates to a stereoscopic viewer and card holder. The device is formed from a scored blank of cardboard to provide a case for holding a plurality of cards with stereoscopic views thereon and the case is provided with an extendable portion which can be raised and held in an upright position. A pair of lenses are mounted in the extension and clips are provided on the opposite side of the case for holding the cards to be viewed through the lenses. The entire structure is slipped into a sleeve container for mailing.

The object of my invention is to provide an inexpensive foldable stereoscopic device having provision for holding a quantity of stereoscopic views and arranged to be set up for viewing the stereoscopic views.

Further objects will appear as the description progresses.

My invention will be further readily understood from the following description and claim, and from the drawings, in which latter:

Fig. 1 is a plan view of the blank for forming the container.

Fig. 2 is a perspective view of the device set up in position for viewing the cards.

Fig. 3 is a view of the container in the envelope.

Fig. 4 is a detail section, taken in the plane of the line 4-4 of Fig. 2, showing the lens mounting.

Fig. 5 is a detail section showing one of the card holders.

My improved device is formed from a blank 11 of cardboard, cut and scored to form a bottom 12, sides 13 and 14, and a top 15. Extending from the side member 13 is an extension 16 having side tabs 17 and a tab 18. When the device is closed the tab 18 is engaged in the U-shaped cut 18'. A pair of apertures 19 having a depression 20 thereabout are spaced in the extension 16 to approximate the spacing of the eyes of an individual and lenses 21 are held in the depressions 20 by means of rings 22 cemented to the face of the extension. End members 23 and 24 enclose the box.

"ice

A suitable number of stereoscopic views on cards can be enclosed in the box and box slipped into a retaining sleeve 25. Seals 26 are attached to the ends of the sleeve for retaining the box therein for mailing.

When it is desired to view the cards the box is withdrawn from the sleeve. The tab 18 is pulled from the top of the device and the extension 16 is raised to an upright position by folding the side tabs 17 at right angles to the extension and engaging the small tabs 27 in the top of the device for maintaining the extension in an upright position. Clips 28 secured to the side portion 14 form holders for supporting the cards to be viewed. The cards are inserted between the clips and the side member 14. An opening 29 is provided in the extension 16 and in the side wall 13 to form a space for the nose of the user.

It will be apparent from the foregoing that I have devised a novel inexpensive combination stereoscopic viewer and container which can be sold as a package containing stereoscopic views and can be quickly adjusted for viewing the cards.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

A stereoscopic viewer and card holder comprising a container having end flaps movable outwardly to form openings for removal of the contents of said container, an extension on said container normally held in flat position on said container by a tab received in a slot in said container, a pair of lenses mounted in spaced relation on said extension, said extension movable from a flat position on said container to an upright position, tabs bendable at right angles to said extension and engaged by tabs in the top for maintaining said extension in said upright position, clips on the side of said container for holding cards in an upright position, an opening in said extension adjoining said container between said lenses, and an envelope for encasing said container for mailing.
